I learned at Southern quilting bees with huge floor frames. I learned how to pull the three layers tight enough that only the edges needed basted, but not so tight that it warped everything. I feel most comfy on a floor frame. I inherited my late MIL's frame and if it weren't bigger than my living room I would have it up right now.
I now have a little lap frame, but I just don't have the same confidence on it for a larger quilt than I have for a floor frame.
You do need to watch out for some things. Either arrange the height of your frame or the chair you are sitting in to make sure you can quilt in a comfortable position. You shouldn't have to reach up and over or bend so low over your quilt. The ones I like best hang from the ceiling, but you can get or make some very good floor frames.
If the price is good and you have the room, I say jump on it. But I have a biased opinion because that's what I learned on.
